At what Celsius temperature will the fuse open?What current ? is needed to transmit 105 MW of power over a transmission line held at a voltage of 25.0 kV? ?= A Find the power loss ?loss that would occur in the transmission line if a 1.45 Ω line is used to transmit 105 MW of power. ?loss= W What percent loss does this represent? percent loss:
- Two 8 awg copper conductors supply a 120v load that's located 225ft from a panelboard. Whats the maximum load in amperes that can be applied to these conductors without exceeding the NEC recommendation for conductor voltage dropAn electric washing machine draws 2.1 A when connected to a 121 V power line. In Arkansas, the average price of electricity is $0.090 per kilowatt-hour. To the nearest cent, how much does it cost to use the washing machine to wash one load of colors and one load of whites if the washing machine runs for 35 min each time it is used? Remember, round to two decimal places, the nearest cent.A toaster is rated at 80.0 W, when connected to a 132.0-V source. What current (in amperes) does the toaster carry?
